Claims. (Cl. 160-128) This invention relates to window construction and particularly to an interchangeable sash and frame construction.

Storm windows and screens have been used for many years and many constructions have been proposed both for interchangeable house windows and screens. Most, if not all, of the constructions heretofore proposed have been objectionable for one or more reasons. Many of the proposed constructions are so complex as to make them prohibitively costly, virtually all must be removed and replaced from the exterior of the building and most have no satisfactory simple means for locking against removal from the outside.

It is an object of the present invention to provide an interchangeable window and screen construction which is simple in construction and free from the complexities of window and screen construction heretofore proposed.

Another object of this invention is to provide a window and screen construction in which the window and screen can be readily interchanged from the interior of the building.

Other objects and advantages of the invention will become apparent from a consideration of the following description and the accompanying drawings in which Figure 1 is a front elevation of a window construction according to the invention taken from the inside of a building on which the sash is used.

Figure 13 is a section on the line 1313 of Figure 12.

Referring to the drawings there is shown an outer 22 adapted to fit in a window frame. Each of the side members 20 is provided with an inwardly directed flange 23 forming a recess 24 within the balance of the stiles. The top rail 22 is equal in thickness to the thickness of flanges 23 on the stiles 20 and the bottom rail 21 is equal in thickness to the depth of the recess 24 in the stiles 20. Each of the flanges 23 on the side member 20 terminates short of the bottom of the sash to form notches or pockets 25.

A window panel having stiles 26, a bottom rail 27 and a top rail 28 is provided to fit within the opening formed by the stiles 20, bottom rail 21 and top member 22 of the sash. Each of the stiles 26 of the window panel is provided with a recessed portion adapted to fit around the inwardly directed flange 23 of the stiles 20 of the window sash. The top rail 28 of the window panel is provided with a recess 29 fitting around the top rail 22 of the window sash. The bottom rail 27 of the window panel is likewise provided with a recess 30 which fits around the bottom rail 21 of the window sash. A pair of lugs 31 project sidewise from the bottom rail 27 of the window panel and engage the notches or pockets 25 in the bottom of the sash when the window is in closed position (see Figure 1). A window pane 32 is mounted in slots 33 in all of the members forming the window panel.

An interchangeable screen panel (see Figure 7) all of the elements of which are identical to those of the window panel except that a screen 34 takes the place of the glass pane 32 is provided to enter the opening formed by the various members of the window sash in the same manner as the window panel described above.

A locking mechanism 35 is provided on each side member of the window sash adjacent the top thereof. Each locking mechanism is made up of a sash engaging member 36 rotatably mounted on a screw 37 or other suitable means and a turning or handle member 38 pivoted in the sash engaging member 36 to lie flat in the plane of the sash engaging member when not in use and to be movable to a position normal to the plane of the sash engaging member when it is desired to turn the sash engaging member into or out of engagement with the Window panel.

When it is desired to place a window or screen panel in the sash the bottom rail 28 of the panel with projecting lug 31 is inserted through the opening formed by the stiles 20, to the bottom rail 21 and the top rail 22 with the lug beyond the inwardly directed flanges 23. The panel is then turned in the opening until the lugs 31 enter the notches 25 in the bottom rail 21 of the sash and the recess in the stiles, top rail and bottom rail of the panel fit around the flanges 23, the top rail 22 and the bottom rail 21 respectively of the sash. The turning member 38 of the locking mechanism is then turned degrees to bring the sash engaging member 36 over the stiles 26 of the panel, thereby locking it in place against removal from the exterior of the building.
